Misspent Youth

Set in the near-future, over three hundred years before Pandora's Star and Judas Unchained, Peter F. Hamilton's Misspent Youth is a gripping introduction to the world of the Commonwealth Saga.
Jeff Baker is granted the gift of eternal youth. However, it's not all it seems…
It is 2040 and, after decades of research, we can finally rejuvenate a human being. At seventy-eight years old, Jeff Baker - renowned inventor and philanthropist - has given the world much of his creative genius. He's therefore selected as first choice for this gift.
At first, rejuvenation feels like a miracle, until the glow begins to fade. Personal relationships start to break down and the world waits for more brilliant new work. Living the dream will come at a cost, but can Jeff pay the price?
